Abstract

Abstract Reaction of 2, 3-dihydro-1, 3-6H-oxazine-2, 6-dione (I) with amines in aqueous medium leads predominantly to N-substituted amides of (Z)-3-carboxylamino-2-propenoic acid. Isomeric 3-(N'-alkylureido)-2-propenoic acids are formed as by-products in the reaction of compound I with ammonia or methylamine; tert-butylamine affords ureido derivative as the sole reaction product. Secondary amines react with compound I substantially more rapidly ...
